<p>Yes, as long as you were happy to wait 30s for an exposure (on tripod), by 1850 (most of those photos were > 15 years later than that) there were many photos of good quality.<p>Look at photos of Crystal Palace in 1851 for example.</p>

<p>It's not new - that was sort of my point with my other comment.<p>At least if it's progressive (so refines and resolves over time), this has been done with pointclouds in the VFX industry in GPU shaders for years in terms of stochastically drawing different points so eventually the whole point set gets rasterised to a fidelity threshold.</p>

<p>> millions of threads<p>Really?! What OSs can handle that many native threads?<p>Also, this seems quite similar to stochastic progressive drawing of pointclouds for realtime that has been done for > 15 years in the VFX industry with GPU shaders in a tiled/bucketed fashion, unless this isn't progressive maybe? (The fact it's been accepted for Siggraph likely indicates it's slightly different).</p>

<p>Hardware's not generally a subscription, monthly cost though.<p>You update it for them every 3/4 years (if they're lucky).<p>It probably makes a <i>bit</i> more sense to compare it to existing software subscriptions like Office, or the old-school 'per-seat' licenses per user for software.</p>

<p>I personally find Fastmail's spam handling a lot worse than GMail's: and I get a <i>lot</i> more spam in my GMail address, due to it being a 22 year old address, which I still use for initial sign-ups, before then changing account emails to my fastmail one after a few months.<p>Very likely a lot of the difference is the types of email each address is getting.</p>

<p>Only with things like -ffast-math enabled will compilers do the reciprocal.
It can make a fair difference in some cases, but it's often better to selectively use it in code locations you know are acceptable by doing it manually in the code.</p>

<p>As someone with a <i>lot</i> of experience in this area doing image processing and rendering for VFX (including writing image readers and writers for my own software and commercial VFX software), I think you might be forgetting that colourspace conversion (to sRGB 'linear' rec709 for old-school SDR, but other more wider gamuts for newer formats) would happen after this, so the 'squish' of the dynamic range would happen after loading.<p>Also, a lot of workflows for image processing and compositing do assume that 0 means zero, whether correctly or not (often incorrectly). So there are often assumptions that for 8-bit, 0u maps to 0.0f and 255 maps to 1.0f for things like masking or alpha: as soon as you have 0 values which become just over 0.0, you then have artifacts because some code somewhere is using a hard threshold of 0.0 to mask some other operation, and vice-versa for 1.0 with alpha, where suddenly because the 255 values are no longer 1.0f, you have very slightly see-through objects (often only visible in certain situations or when pixel-peeping) after pre-multiplication.<p>(Same thing can happen when 254 becomes 1.0f after +0.5 with masking).</p>

<p>If you're a beginner, or just want something which works quickly, sure.<p>However OIIO is far from perfect in all situations (having had to debug and fix issues with its mip-map generation filtering code in the past), so don't always assume that just because there's a mature open source library out there doing something that it's always perfect.</p>

<p>Why are people down-voting this?<p>It's generally correct: If you're self-employed / sole trader and operating outside IR-35, there's no way the HMRC can know how much you were paid as they don't have the info, so they can't know how much tax you owe.<p>In other situations for payrole / salary (like PAYE for example) they do have the info, as companies have to submit it, so generally people in those situations don't have to submit tax returns (unless they have significant capital gains).<p>I do think it's a bit annoying you have to declare tax on interest since 2016 if it's over £1000 - previously banks would take it out automatically, and this is still done in other countries (NZ for example).</p>
